So yesterday, Thunderlips was having issues with data connectivity. It would randomly connect and disconnect all throughout the day. First I assumed it was a tower issue post storms the night before. As day went on it goy worse and worse. I contacted straight talk people and they had me remove everything out of the APN settings except the APN name as att.mvno. No proxy server, no port nothing. Once removed, cycle data connection and I am up! Thought I share in case anyone else runs into this.
